Several types of mechanically actuated switches have been proposed for this purpose. For example, U.S. %fF No. 3,719,788, issued March 6, 1973, discloses a cam-actuated switch with a metal contact member supported by a cam follower cantilevered to a circuit board. are doing. a rotatable cam engages a cam follower;
When the cam's dowel is engaged, its metal contact member is pressed into contact with two conductive paths on the circuit board, establishing an electrical connection between the four conductive paths. In order to establish a stable electrical connection with this type of switch, the cam follower and cam dwell must be engaged so that each time the switch is actuated, the metal contact member and the underpass must be connected. It is necessary that the contact pressure is constant. Camshafts require precision bearings to provide stable contact pressure. If the same (7) cam shaft is used to operate several switches, even if the cam itself is a precision component, the plane of the circuit board must also be flat within a sufficiently small tolerance. , the above contact pressure will be constant for each switch as long as it is parallel to the rotational axis of the cam. Furthermore, because the cam follower is cantilevered, it is difficult to achieve and maintain proper alignment of the metal contact member and the conductive path.

It is made using a technique similar to that disclosed in US Pat. No. 4,150,420. A contact strip (6) is formed on a 35-noodle polyimide tape (5o). For example, tape (
5o] by optical processing and etching,
A strip of copper may be formed at the desired location as the contact strip (6), and gold may then be applied non-electrically to the copper strip as a finishing touch to the contact strip (6). The chip f (50) is placed in the mold so that the upper surface (the surface on which the contact piece (6) is exposed) faces the outer surface of the mold. Two parallel grooves are formed on the glossy surface of the mold that determines the shape of the mold. When Ela Otoma, an elastic material, is injected into the mold from the back of the tape (50), this elastic material The pressure forms the tape into a contour that follows the grooves on the entire surface of the mold. This elastic member made of silicone rubber is strongly pressed against the polyimide tape (50). Therefore, when the elastic material hardens, the elastic material with longitudinally extending ridges (56) and the polyimide tape are combined into an elongated object (52).
) is formed. Blocks each having two contact pieces are cut out from the object (52) to form individual contact members (2), and a rectangular through hole (54) is drilled between the two contact pieces (6) of each block.
